   Question

   Recent research has shown that lecturers are among the most stressed workers. A researcher wanted to know exactly what it was about being a lecturer that causes this stress and subsequent burnout. She recruited 75 lecturers and administered several questionnaires that measured the following variables:  Burnout  (high score = burnt out),  Perceived Control  (high score = low perceived control ),  Coping Ability  (high score = low ability to cope with stress), Stress from Teaching (high score = teaching creates a lot of stress for the person), Stress from Research (high score = research creates a lot of stress for the person), and Stress from Providing Pastoral Care (high score = providing pastoral care creates a lot of stress for the person). The outcome of interest was burnout. Cooper’s (1988) model of stress indicates that perceived control and coping style are important predictors of this variable. The remaining variables were used as predictors in the regression to see the unique contribution of different aspects of a lecturer’s work to their burnout.

   Which of the predictor variables has the strongest effect on burnout according to the output shown below?

   

   

   
   
   1. FALSE: Perceived control because it has the highest unstandardized coefficient
   2. TRUE: Coping ability because it has the highest standardized coefficient
   3. FALSE: Stress for teacing because it has the highest absolute value of the standardized coefficient
   4. FALSE: None of the other options is correct
   
   

   Solution

   When we want to compare the effect of different variables in the same regression, we use the standardized coefficient (beta). As shown in the table of the coefficients, the variable Coping Ability has the highest beta (0.663).
